Rotoscope vs Stop Motion
ロトスコープ / ストップモーション
Both sit in Animation Techniques, so the question is not what they belong to but how they behave. Both are read here as technique. They are reached for with some of the same intent, which is where they get confused.
Rotoscope
Tracing live-action footage frame by frame. Patented by the Fleischers, it mixes the gravity of live action with the freedom of drawing into a distinctive wavering line.
Stop Motion

Moving puppets and models one frame at a time to give matter life. The faint tremor of handwork and the presence of real materials remain a charm CG cannot replace.
| Rotoscope | Stop Motion | |
|---|---|---|
| Era | 1915– | 1898– |
| Family | Animation Techniques | Animation Techniques |
| Kind | Technique | Technique |
| Cues | Movement from live action / Wavering contours / Bodies with weight / Between film and drawing | Frame-by-frame shooting / Real models and textures / A faint tremor / Miniature lighting |
| Best used for | Showing the weight of human gesture or a crowd while staying in drawing · Converting live footage into drawing for reasons of texture or rights | Food and household product ads that must keep the feel of real material · Shorts and music videos where the warmth of handwork is the point |
| Type | Redraw the lettering every frame so it wavers with the artwork | Build the lettering as a physical object and light it with the set |
| Composition | Do not keep the live framing, redraw the background to clean it up | Shallow depth of field, with the miniature scale left visible |
| Material | Vary the line weight and let the contour keep wavering | Fabric, clay and paper chosen to hold up under close inspection |
| Caution | Tracing without deciding what a drawing should keep and what it should drop, so the movement is accurate and the image has nothing to look at. | Smoothing away every tremor and fingerprint until the result is something computer graphics would have produced faster and cheaper. |
